RESUMEN Objetivo analizar la evolución espacio-temporal de la mortalidad por accidentes cerebrovasculares (ACV) en Minas Gerais, 1980-2021. Métodos estudio ecológico, con datos por microrregión. En el análisis de tendencia se utilizó regresión lineal segmentada, en el análisis espacial estadística scan. Resultados Hubo 392.521 muertes por ACV (tasa de 52,6/100.000-años). Todas las tasas (bruta, ajustada, grupos de edad) indicaron una tendencia decreciente, con menor velocidad en tasa bruta (Variación Porcentual Anual [VPA] = -0,70), mayor en el grupo de 20-39 años (VPA = -4,48). Se identificó un conglomerado con tasas altas en el sur (1980-1999; Riesgo Relativo [RR] = 2,06) y uno con tasas bajas en el noroeste (2008-2021; RR = 0,59). El descenso fue más intenso en el sur (VPA = -3,64). Conclusión Se observó tendencia de disminución de mortalidad. La identificación de conglomerados y áreas con mayores tasas en el noreste en los últimos años merece la atención de los gestores.

RESUMO Objetivo Analisar a evolução espaço-temporal da mortalidade por acidente vascular cerebral (AVC) em Minas Gerais, 1980 a 2021. Métodos Estudo ecológico, com dados agregados por microrregião. Na análise de tendência, foi utilizada regressão linear segmentada; na análise espacial, mapas com taxas quinquenais e estatística scan. Resultados Ocorreram 392.521 mortes por AVC (taxa de 52,6/100 mil habitantes-ano). Todas as taxas (bruta, ajustada, por faixas etárias) apresentaram tendência de diminuição, com velocidade menor na taxa bruta (variação percentual anual [VPA] = -0,70) e maior na faixa etária de 20 a 39 anos (VPA = -4,48). Foi identificado um conglomerado no sul com taxas altas (1980-1999; risco relativo [RR] = 2,06), e no noroeste, com taxas baixas (2008-2021; RR = 0,59). A diminuição foi mais intensa no sul (VPA = -3,64). Conclusão Verificou-se tendência de diminuição da mortalidade por AVC. A identificação de conglomerados e áreas com maior risco no nordeste do estado, nos últimos anos, merece atenção dos gestores.

ABSTRACT Objective To analyze spatio-temporal evolution of stroke mortality in Minas Gerais state, Brazil, 1980-2021. Methods Ecological study with aggregated data by micro-region. Segmented linear regression was used for trend analysis; maps with rates per five-year period and scan statistics were used for spatial analysis. Results There were 392,521 stroke-related deaths (rate of 52.6/100,000-year). All rates (crude, adjusted, by age group) showed a decreasing trend, less so in the crude rate (Annual Percent Change [APC] = -0.70) and a faster decrease in the 20-39 age group (APC = -4.48). A high-rate cluster was identified in the southern region (1980-1999; Relative Risk [RR] = 2.06), and a low-rate cluster in the northwest (2008-2021; RR = 0.59). The most significant decrease occurred in the south (APC = -3.64). Conclusion Stroke mortality showed a decreasing trend. Clusters and areas with higher rates identified in the northeast in recent years require attention by service managers.

Abstract: Income variables from the Brazilian population census (IBGE) are often used as proxies for the population’s socioeconomic level in spatial analyses of urban segregation, inequality and social exclusion. However, income variables are dependent on reference values (minimum wage) that change over time, which can be challenging for multitemporal analysis. This paper discusses this issue and proposes a methodology to adjust income data that allows a meaningful comparison between the datasets of two Census periods. The methodology was applied to five medium-sized cities of the state of São Paulo by adjusting income data from Census 2000 and 2010 according to the period’s inflation rates. The analysis shows that the methodology mitigates the comparability issues. Results better reflect the changes in population composition and in residential patterns of different income groups that took place over the 2000s in Brazil in medium-sized cities.

Abstract The amount of researchers and scientific papers rapidly grows, annually. The metrics to analyze the quality and quantity of these publications have consolidated in the academic world. A bibliometric mapping of scientific papers on Geographic Information Systems (GIS) published between 2007 and 2016 was carried out. The sample analyzed 2,053 papers, extracted from twenty journals of the Web of Science Core Collection platform. The following were evaluated: total number of publications, production by area of knowledge and by country, authors, periodicals and the most cited words. The results shows that 2012 and 2013 were the most productive periods, and that the annual growth rate of publication was 1.8%. The most significant academic areas were Geography, Computer Science, Physical Geography, and Environmental Sciences/Ecology. The three major publishing clusters were North America, Western Europe, and Eastern Asia. The International Journal of Geographic Information Science was considered the most important journal. The most relevant topics were cellular automata, relationship between GIS and users, integration of GIS with remote sensing, different land use classification methods, and critical reflections on technologies and GIS.
